I would guess that you are using the Washington University IMAP daemon, which has unfortunately chosen to treat your entire home directory as a possible mailbox -- what is probably happening is that you are not really hung, but are stuck running stat() on every file under your home directory. To test this, add a new, bogus user to your system, and clean out any "skeleton" cruft from ~/bogus. Try logging in to WorldPilot -- if that works, then you need to search the archives from February for notes on WU IMAP. > > Trimming the contents of my mailbox down to just 6 messages didn't > seem to make any difference. > > Anyone shed any light? > > Oh yes, I have applied the imap.py.diff patch to the python library. -- =========================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

I'd keep the drop-down menus in javascript. You can do similar things in zope (i.e. the tree tag or the tab bar at the top of the management interface), but then every change is a fetch back to the web server. If you keep the javascript then it all happens at the client. If you want you can generate the javascript with dhtml. That way the contents of the menus can follow your site. You'd have to set the comtent type so that the browser thinks it is javascript. (hmm, how is javascript cached??) -- cary [snip]

nested dtml-in with sql method -namespace problem (?)

hi all, i have posted this question a while back, but got no replies. maybe imy question is a bit off or unclear. so here it is again. rephrased. i have 2 sql methods. sql1, and sql2. sql 2 got the parameter for it's query from sql1. as follows: -- <dtml-in "sql1"> <dtml-in "sql2(obj=myobj)"> do stuff </dtml-in> </dtml-in> -- sql1 is just a query that returns myobj that will be used by sql2. this used to work on 2.1.6 but not anymore on 2.2 i guess tmyobj is not in the namespace. even tried passing _.None, _,obj=myobj but resulted the same error. the traceback raceback (innermost last): File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/kdie/Zope-2.2.0b1-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/OFS/DTMLMethod.py, line 168, in __call__ (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_String.py, line 500, in __call__ (Object: index_html) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_In.py, line 611, in renderwb (Object: qry_msgs_by_par_id(par_id=0)) File /home/kdie/Zope-2.2.0b1-src/lib/python/OFS/DTMLMethod.py, line 164, in __call__ (Object: show_subtree_index) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_String.py, line 500, in __call__ (Object: show_subtree_index) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_In.py, line 633, in renderwob (Object: qry_msg_thread(par_id=obj_id)) File /home/kdie/Zope-2.2.0b1-src/lib/python/DocumentTemplate/DT_Util.py, line 339, in eval (Object: qry_msg_thread(par_id=obj_id)) (Info: qry_msg_thread) File <string>, line 0, in ?

SMTP server external method??
by Jon Brisbin 18 Jun '00

18 Jun '00

Has anyone attempted a python-based SMTP server that creates a Zope object immediately upon recieveing email??? If not, how do you handle email in zope for a web-based system?? just periodically create objects from the contents of /var/spool/mail/user ... or use some other method?? ideally, the object's various properties would be set upon instantiation...stuff like header fields would correspond to properties...etc... For those that handle email in Zope, how do you approach this?? thanks!! Jon Brisbin jbrisbin.net

Josh, This is a "zope(a)zope.org" question, not a "zope-dev(a)zope.org" question, so I've moved the thread to there. You can do what you want in a couple of ways: 1: Cookies Can your HTTP clients use Cookies? You can send a cookie on one page and retrieve it on the next. Look at the "Zope Developer's Guide" and for information on Cookies and the RESPONSE variable. Watch out though -- if you pass data in a cookie, and expect to use that data retrieved later, you could be opening yourself up to a security risk. A client could change the data in the cookie to mean something different, and you might never find out. 2: Sessions Use one of the NNNSession products, such as FSSession or SQLSession. These use cookies behind the scenes, but present you with a nice programming interface. Also, your actual data (session variable and so forth) live on the server. The cookie just tells the server where to find them. Thus, no part of your data is entrusted to the client. I'd suggest you look at the FSSession product: http://www.zope.org/Members/gaaros/FSSession Or perhaps HappySession: http://www.zope.org/Members/hungjunglu/Products/HappySession -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

From where does nothing spring from?
by Graham Chiu 17 Jun '00

17 Jun '00

I am trying to add some data validation methods to my fieldProduct ( www.zope.com/Members/gchiu ) - a data entry class. I have added a method called isNotEmail which returns either a 0 or a 1. Here's the method definition: <dtml-if "_.has_key(fieldName)"> <dtml-call "REQUEST.set(_[fieldName],_.string.lower(_[fieldName]))"> <dtml-if "_.len(_[fieldName]) <8 or _.string.find(_[fieldName],'@')==-1 or _.string.find(_[fieldName],'.')==-1 or _.string.rfind(_[fieldName],'.') < _.string.find(_[fieldName],'@') or _.string.find(_[fieldName],'nospam') > 0 or _.string.find(_[fieldName],'..')>0 "> <dtml-call "REQUEST.set(_['fieldNameError'],'This is not a valid email address. Please amend.')"> <dtml-return "0"> <dtml-else> <dtml-return "1"> </dtml-if> <dtml-else> <dtml-call "REQUEST.set(_['fieldNameError'],'You need to supply a <b>valid</b> email address')"> <dtml-return "0"> </dtml-if> where fieldName and fieldNameError are properties of the class. However, when I call the method <dtml-var "REQUEST.set('error',f_Email.isNotEmail(f_Email,_))"> where f_Email is an instance of the product, then the words 'None' are returned as well, and render to the screen. Where is this coming from? -- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.co.nz/index.php Powered by Interbase and Zope

Is these available in Zope or is there some >way of using these. Javascript is client based, whereby Zope handles only server-side activities similar to CGI. You usually have no way to replace Javascript, except in a few places. >Is there some book released on zope/DTML for reference. There is the ZDP (http://zdp.zope.org) which includes the ZQR (Zope Quick Reference) that lists all the tags, but is outdated. We are currently working on a model to include a DTML reference into the Zope Online Help System. That should appear at the end of the summer in the Zope distributions. >Does this mean a complete rewrite of the code is required of all the >javascript and cgi files , or is there some method to convert them to >DTML. Yes, you have to convert everything to DTML by hand. If you understand Zope well, you will find that you can do many thing easier and shorter in Zope. For most everyday tasks you have usually already a product written for you. I think before converting the entire site you should first learn Zope and Python till you feel comfortable and then redesign your site from scratch, since Zope's advanced features and object model will allow you to do things differently (read: The right way!).

Python class browser
by Cary O'Brien 17 Jun '00

17 Jun '00

I'm tired of digging through .py files to find what methods a class supports. Has anyone put together a class browser ZClass w/ external methods that allows you to look at modules, classes, methods, and method arguments via the browser? It *seems* as if python supplies all the pieces (i.e. start with sys.modules and use the pyclbr stuff from there). -- cary
